Application filed October 7, 1910, Serial No. 585,746. Renewed June 24,1912'. Serial No, 705,639.

To all whom it may concern Be it known that I, WVILLIAM .H. Brown, ofSyracuse, in the county of Onondagaand State of New York, have inventeda certain new and useful Decimal Mechanism for Cal culating-Machines, ofwhich the following is a specification.

My invention relates to calculating machines and has for its object theproduction of a particularly simple and efficient decimal mechanismtherefor; and it consists in is movable axially tions,

the combinationsand constructions hereinafter set forth and claimed.

In descrlbing this invention reference 1s had to the accompanyingdrawing in whichlike characters designate corresponding parts in all theviews. 1

Figures 1 and 2 are plan views 'of a portion of a calculating machineprovided with my decimal mechanism, the controlling and calculatingwheels being shown in different denominational relations. Fig. 3 is asec-- tional view on line'A-A Fig. 1, other parts being added. Fig. 4 isa'sectional view on the plane of line 13-13 Fig. 1 looking to the left,portions. being omitted and portions being shown in dotted .lines, thekey connections between the key. and decimal mechanism being also shown.Fig. 5 is a view-similar to Fig. .3, showing the key as depressed andthe decimal mechanism as in operative position. Fig. 6 is an endelevation of the actuatlng member shown 1n Figs.

1 and 2. Fig.7 IS a fragmentary view of a portion 'ofthe laterallymovable carriage for the controlling wheels, and contiguous p r s 1 isahseries bf calculating wheels, 2, a series of [controlling wheels orelements mounted upon the shaft or carriage 3, which to the leftrelatively to the calculating wheels for shifting the controlling wheels2 laterally into denominational positions. Said wheels 2 are movableabout the shaft into numerical posit ons, and with theshaft from theirnumerical posi- 1. The calculating wheelsare normally out of mesh withthe controlling elements'or *heels', and, after the controlling wheelshave been set in their and for actuating the calculatingwheelsdenominational and Patented Nov. 16, 19.15. 1

set controlling wheels in any suitable man-- As themeans forcontrollingithe movement of the controlling wheels 2 to the left and themeans for controlling the, movement of the calculating Wheels into andout; of mesh with the controlling wheels, form no part of my presentinvention, and as the' movement of controlling wheels step by step intodenominational positions and the relative movement of calculating wheels,and.

controlling Wheels relatively to each other,

essary. The controlling wheels 2 held from movement into numerical posiWhen the controlling series 2 is moved laterally, the

. shoulders 4 are moved off the end of the holding means and the wheels21'are'v free to is ,well known to those skilled in the art, it is fthought that further description is unnecare normally move into theirnumerical positions, Fig. 3, from which they are actuated in a retrograde direction by suitable means consisting of rock' arms 5 on theshaft 3. and an armfi connecting the ehdsof the rock arms'and extendingparallel tothe shaft 3 and across the peripheries of the wheels 2 inrear of said shoulders 4, said arm 6 having a roller 7 thereon. 'As theshaft 3 is rotated the lastmentioned arm 6 moves through an arc and theroller 7 engages the shoulders 4 of the calculating elements 2'. As hereshown the holding means consists of a crank arm 8, 011 e shaft 9,]o'urnaled in the frame 10- and having an arm or device 11 extending parallel to the shaft and engaging saidshoulders, and aspring 12 forresisting the movement of. the rock arm. When the controlling seriesis'shifted 'a predetermined num-v ber of steps to the right ashereinafter explained, the shoulders 4 of the-two elements at therightof said series 2'.Will be moved under the holding device 11g'so'that during the retrograde movement of the elements by the shaft 3,said two elements, to the right will jengage' 'the' holding device 11and rock the device llout of the 'ders 1 of said elements.

t The vcontrolling wheels are limited in their numerical positions inany suitable manner as by a series of stops 15, for each .whee'l2,.the.stops of each series represent ing yalues from 0 to 9 inclusive.As seen in F 1g. 3, said stops are normally arranged flush with theconcave face 16 of the support 17 carried by and movable laterally withthe shaft 3, and are said face 16 into the path ofthe shoulder 4: of thecorresponding wheel 2. These stops are moved into the path of theshoulders 4; by rock shafts 18 corresponding in number to the number ofstops 15 in each series, each rock shaft 18 having a rock arm 19 forcoacting with a certain stop of each series. Each' rock shaft 18 isoperated by a key as 20 connected thereto by a link 21, which is pivotedto an arm 22 on each rock shaft. The stops 15 are depressed out of thepath of the shoulders 4 into their normal positions by. the roller 7 onthearm 6 when said roller is being operated to actuate thepreviously-set controlling wheels 2 in a retrograde direction to theirstarting position.

The shaft 3 1s rotated by an actuating member movable about an axiscoincident with said shaft, and comprises a sleeve 23 mounted on theshaft 3 and connected to the shaft 3 by a feather 21, Fig. 6, provided,

on said shaft and extending into a comparatively wide way 25 in thesleeve 23 for forming a lost motion connection between the sleeve'23andthe shaft-3. An operating handle 26 is mounted on the sleeve 23.

i The decimal mechanism consists of means for moving the carriage 3laterally in a "retrograde direction (that is in a direction opposite tothe movement of the carriage when shifting the elements 2 lnto thedenominational positions) a predetermined number of steps usually, two.steps. Preferably the controlling series is normally arranged to theright of the calculating series,

having its two elements tothe extreme left arranged opposite to the twoelements at the extreme right of the calculating series, Fig. 1. Thusthe two wheels at the extreme right of the calculating wheels 1 arealways decimal or cents wheels.

As here shown the decimal mechanism comprises power transmittingconnections between the actuating member 23 and the carriage on shaft 3whereby the carriage is shifted'to the right a predetermined distanceafter the elements 2 have been shifted into denominational positions andprelimitheir numeri al positions,

movable above nary to the actuatien of said elements from such shiftingto the right movlng some of the'elements in denominatlonal positions,out of such posi-' ,tions, and into decimal positions. As seen 1n Figs.1, 2, 4: and 5, the connections preferably include a part as .a lever 27coacting actuating member 23. The part 28 is also provided with asurface 34 concentric with the axis of said part 28, and, so far asthis.

invention is concerned said surface 34 serves as a guide upon which saidroller 32.rides.

after moving out of engagement with the cam surface 33. The other arm-35of said lever carries a clutch member 29 movable in aguide thereinbeyond the end of said arm 35 into any one of a series of sockets ornotches 36, Fig. 7, formed in the shaft 3,

and corresponding in number to the number less two of the controllingelements 2. Said arm 35 isalso formed with an extension 37, Figs. 4 and5, projecting across the shaft 3 and into the path of a shoulder 38,Fig. 7 on the shaft 3. As here shown the shoulder 38 is the end of thefeather 24 which .connects the shaft 3 and the hollow shaft or sleeve'23.

The lost motion before referred to, permits the cam 28 to move the lever27 on its pivot before the actuating member 23 starts the rotation ofthe shaft 3 to actuate the controlling elements. W hen the slidingclutch member 29 is in one of the sockets or notches 36, and the hollowshaft 23 is operated, the shaft 3 will be moved-axially to.

the right by the cam surface 33, and the bell-crank lever 27, and, afterthis axial movement is completed, the lost motion between the sleeve 23and shaft 3 is then taken up, so that the shaft 3 is rotated, causingthe periphery of the shaft 3 to engage and push the sliding clutchmember 29 out of the socket or notch 36. I

The clutch member 29 is' operated bymeans of a key 39 and connect-ionsbetween the key 39 and said clutch member 29, said connections beinghere shown as a rock shaft 10 supported by the frame piece 31 and havingoppositely-extending rock arms 41 and 42, one of which is connected tothe key lever 39 by a link 43, and the other of which 1 enters-a recess44 in the arm 35 of the bell crank lever and engages the end of thesliding clutch member 29, Figs. 4 and 5. Obviously as the key lever 39isdepressed the an; is will is pulled to a movement-oi the controllingwheels into denoniinational positions, is prevented by a stop elo fixedto the frame piece 31 and arshaft 23 by the hand lever ranged inalinement with the recess 4% of the arm and in the path of the tail -l$of the clutch member 29, so that when the ex tensionBl of thearm isengaged by the shoulder 38, furthermovement ot' the shaft .3, LSprevented, notiitymg the operator that the shaft can shift two moresteps to the left and that tl ese two steps are reserved for decimals orcents "1 By operating the decimal key 39, the clutch member. :29 isthrown into one of the sockets 36,- so that its opposite end or tail i6is out of the path of the stop so, in order that the wheels 2 may bemoved two more steps the left for carrying the two wheels in. which thedecimalfigures are set, oil the end of the device 11. Upon the operationof the main shaft by the ieyer 26 the carriage 3 will be carried twosteps to the right. 4

in, operation the decimal key 39 maybe operated to throw the clutchmember 29 into one of the notches 36 at any point in the lat eralshifting of the shaft. 3. This shifting is fully explained in my pendingapplication referred to. If the decimal key is depressed before any ofthe numeral keys have been operated and consequently before any lateralshifting oft-he shaft 3 has taken place, the clutch member will enterthe first notch 36 to the leit, and the number. set up in the wheel 2.will contain two figures'and Will be a decin- .l, as the shaft 3 canshitt but two steps to the leitt before the roller 32 on one arm of thebell-cranklever :27

engages the cam face and limits further pi otal movement of thebellcrank lever 2'7 and consequently further shifting to the left of theshaft 3. Upon the operation of the 26, the cam surface actuates the bellcrank lever 21' suficiently to carry right bet-ore the lost motionbetween the shafts 23 and 3 is taken up. If the decimal key 39 depressedafter the shaft 3 has shifted one step to the left by the depression ofa numeral. key as 20, the clutch member 29 will enter the second notch36 from the left and the mimber setup in. the wheels 3 Wil contain onewhole number and a decimal. Thus the notch that the clutch member 29enters, depends on the number of whole numbers in the example set up inthe wheels 2.
